The first thought is that its impossible to know whether the train is coming or going. The second is that if this isn't a set-up, which I suspect it isn't somehow, then I think you perhaps need to go into b/w territory: it at least gives an edge of reportage that makes the ordinary more interesting - and this is fairly ordinary, really; and perhaps use processing to pull out the sense of those out-stretched arms, whicha are the real point of this scene - they're what communicates your message here. Keeping the far side of the tracks properly exposed is useless if it means relegating her pose into the shadows. If it was set-up, then you needed to capture some motion in the train, at the very least, as well as putting more into the compositional elements.
You've got the concept of "too late" working.
Could use a bit more contrast in your forground figure. Maybe a brightly colored coat would have helped, not only to bring the figure forward, but also to tie it to the train. Also, I think it would have been nice if the clock were more prominant.
